db2 discussion

We have developed a Debezium connector for usage with Db2 which is now available as part of the Debezium incubator. Here we describe the use case we have for Change Data Capture (CDC), the various approaches that already exist in the Db2 ecology, and how we came to Debezium. In addition, we motivate the approach we took to implementing the Db2 Debezium connector.

In this blog post, we are going to discuss how Delhivery, the leading supply chain services company in India, is using Debezium to power a lot of different business use-cases ranging from driving event driven microservices, providing data integration and moving operational data to a data warehouse for real-time analytics and reporting. We will also take a look at the early mistakes we made when integrating Debezium and how we solved them so that any future users can avoid them, discuss one of the more challenging production incidents we faced and how Debezium helped ensure we could recover without any data loss. In closing, we discuss what value Debezium has provided us, areas where we believe there is a scope for improvement and how Debezium fits into our future goals.

Integration Scenarios with Debezium and Apache Camel Integration Scenarios with Debezium and Apache Camel

One of the typical Debezium uses cases is to use change data capture to integrate a legacy system with other systems in the organization. There are multiple ways how to achieve this goal

Write data to Kafka using Debezium and follow with a combination of Kafka Streams pipelines and Kafka Connect connectors to deliver the changes to other systems
Use Debezium Embedded engine in a Java standalone application and write the integration code using plain Java; that’s often used to send change events to alternative messaging infrastructure such as Amazon Kinesis, Google Pub/Sub etc.
Use an existing integration framework or service bus to express the pipeline logic

This article is focusing on the third option - a dedicated integration framework.

Release early, release often! After the 1.1 Beta1 and 1.0.1 Final releases earlier this week, I’m today happy to share the news about the release of Debezium 1.1.0.Beta2!

The main addition in Beta2 is support for integration tests of your change data capture (CDC) set-up using Testcontainers. In addition, the Quarkus extension for implementing the outbox pattern as well as the SMT for extracting the after state of change events have been re-worked and offer more configuration flexibility now.

It’s my pleasure to announce the release of Debezium 1.1.0.Beta1!

This release adds support for transaction marker events, an incubating connector for the IBM Db2 database as well as a wide range of bug fixes. As the 1.1 release still is under active development, we’ve backported an asorted set of bug fixes to the 1.0 branch and released Debezium 1.0.1.Final, too.

At the time of writing this, not all connector archives have been synched to Maven Central yet; this should be the case within the next few others.
